For one of my project, I am placing WiFI nodes at some arbitrary points and WiFi Tag(RTLS) is carried by a person.Whenever WiFi Tag is in the vicinity of the WiFi Node, WiFi Node has to communicate to the HOST that WiFi tag is in its zone, its dependent on received Signal strength.WiFi Node continuously scans for new WiFi signal, whenever WiFi Tag signal strenth is more, WiFi node sends this information to the HOST.How should we do this?Please let me know your views.
